Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164028, here are decompositions:

5 + 164023 = 164028
17 + 164011 = 164028
31 + 163997 = 164028
37 + 163991 = 164028
41 + 163987 = 164028
47 + 163981 = 164028
101 + 163927 = 164028
127 + 163901 = 164028

Showing the first eight; more decompositions exist.
